D2 is a very abrasion resistant alloy tool steel, the Vanadium does that and is the reason many of the newer steels have it in the alloy. Two 2 hour tempers for D2 @400 will result in about a 61-62 hardness and for this alloy it won't be brittle to the point of being a problem like I have dropped a file and it broke, but it would be pretty file resistant, in other words a file would pretty much skate over the edge. The first air quench knife I ever made was D2 and I had it done by a professional heat treater. It made me go buy a diamond sharpener as it took a lot of effort with a medium India stone to get it sharp.
